摘要：

Ba0.5Sr0.5TiO3-Zn2TiO4 composite ceramics with low dielectric constant and high tunability are fabricated at a relatively low sintering temperature of 1200 degrees C via the conventional solid-state reaction route. Zn2TiO4 and Ba0.5Sr0.5TiO3 can be friendly coexistent in the composite material system. The dielectric constant is tailored from 2500 to 83 by manipulating the addition of Zn2TiO4 content from 0 wt.% to 80 wt.% weight ratio. The dielectric loss still keeps around 0.002 and the tunability is 10.3% under a DC-applied electric field of 30 kV/cm at 10 kHz for the 80 wt.% Zn2TiO4 added Ba0.5Sr0.5TiO3 composite ceramics. These composite ceramics are promising candidates for multilayer low-temperature co-fired ceramics (LTCC) and potential tunable devices applications. (C) 2010 Elsevier Ltd. All rights reserved.
